"Multiproduct formulas and Trotterization"

Presented by Jacob Watkins, Michigan State University

Monday, January 31, 2022, 2:00 pm — Videoconference / Virtual Event (see link below)

Abstract: I will discuss a new quantum algorithm for simulating time-dependent Hamiltonians, one which uses so-called multiproduct formulas as the primary ingredient. Multiproduct formulas extend the more familiar product formulas (such as Suzuki-Trotter decompositions) by taking sums of them, with more terms increasing the simulation accuracy. After giving a broad overview of quantum simulation in general, including some basic notions and definitions, I will show how one can use multiproduct formulas for time-dependent systems, and present both theoretical and numerical characterizations of the algorithm's performance. Along the way, I will make use of an interesting concept: time-dependent systems can be formally treated as time-independent ones embedded in a larger Hilbert space.

Nuclear Physics Seminar

"Flavor physics in the forward region: LHCb highlights from the pandemic"

Presented by Cameron Dean, LANL

Tuesday, February 1, 2022, 11:00 am — Videoconference / Virtual Event (see link below)

Abstract: The pandemic has dramatically changed the world's approach to work life. One difference noted by those in the high energy community was an increase in time devoted to physics analyses. This talk will focus on three papers produced by the Los Alamos LHCb team during the pandemic; the observation of time-dependent CP violation in B_s0 mesons, multiplicity-dependent modification of tetraquark candidates and the separation of chi_c states in heavy ion collisions.

"EFT Constraints from Neutrino Experiments"

Presented by Zahra Tabrizi

Thursday, February 3, 2022, 11:00 am — Videoconference / Virtual Event (see link below)

Abstract: We will discuss how to systematically study physics beyond the standard model (BSM) in the neutrino experiments within the Standard Model Effective Field Theory (SMEFT) framework. In this way, the analysis of the data can capture large classes of models, where the new degrees of freedom have masses well above the relevant energy of the experiment. Moreover, it allows us to compare several experiments in a unified framework and in a systematic way. Our proposed approach could be applied to several short- and long baseline neutrino experiments. We will show the results of this approach at the FASERv experiment, which will be soon installed 480 m downstream of the ATLAS interaction point, as well as the medium baseline reactor experiments Daya Bay and RENO. For some coupling structures, we find that these neutrino detectors will be able to constrain interactions that are almost three orders of magnitude weaker than the Standard Model weak interactions, implying that they will be indirectly probing new physics at the 10 TeV scale.

Particle Physics Seminar

"Detecting Relic Neutrinos from the Big Bang"

Presented by Andi Tan, Princeton University

Thursday, February 3, 2022, 3:00 pm — Videoconference / Virtual Event (see link below)

Abstract: Neutrinos produced in the early moments of the Big Bang are believed to be the second most abundant particle in the Universe. PTOLEMY is an experiment for detecting relic neutrinos captured on tritium targets to map the flux of neutrinos on the sky. The challenges of ultra-cold relic neutrino detection have led to new advances in material technologies, RF detection, and a transverse drift electromagnetic spectrometer. The current status and outlook of PTOLEMY are presented.

NT/RBRC Seminar

"Pseudo- and quasi-PDFs in the BFKL approximation"

Presented by Dr. Giovanni Chirilli, Regensburg University

Friday, February 4, 2022, 9:00 am — Videoconference / Virtual Event (see link below)

Abstract: To calculate the PDFs from first principles in Lattice gauge theories it is convenient to consider the Ioffe-time distribution defined through gauge-invariant bi-local operators with space like separation. Lattice calculations provide values for a limited range of the distance separating the bi-local operators. In order to perform the Fourier transform and obtain the pseudo- and the quasi-PDFs, it is then necessary to extrapolate the large-distance behavior.

I will discuss the formalism one may use to study the behavior of the Ioffe-time distribution at large distances and the behavior of the pseudo- and quasi-PDFs at low Bjorken-x. Using light-ray operators, I will also show how to obtain the behavior of the leading and next-to-leading twist approximation of the pseudo- and the quasi-PDFs at low-xB.
